I'm quite stuck with this problem.
I know that I have an object in orbit. I know the eccentricity of that orbit, as well as the semi-major axis of the orbit.
Giving a true anomaly, how do I find the speed and altitude of that object? The true anomaly is the angle between the line made with the focus of the ellipse and the position of the object.
P.S. I'm more looking for a general help, more than a specific answer. That's why I didn't give any numbers.
